When I'm trying to install AjaxMin from Nuget for __Web Site project__ in VS2012, I got this error:

It was only happened for __Web Site project__ only. And for VS2010, the package are downloaded and there is no error message, but AjaxMin.dll file is never copied into Bin folder, and error occurred when I'm trying to uninstall the package.
Everything works fine on __Web Application project__.

Any chance of attaching a larger picture and/or transcribing the error message? I can't read it; it's too small.
